摘要
L293D是一种直流电机控制器件,该器件具有外围电路简单、易于集成、控制等特点,本设计是在单片机SPCE061A的基础上,扩展了两片L293D构成了护士移动机器人主控电路板,同时也扩展了电源,确保L293D为电机供电。实际测试中,L293D对电机的控制效果良好。
L293D is a DC motor controlling chip with simple external circuit, easy to be integrated. In this design, based on MCU SPCE061A, two pieces of L293D are adopted in the main controlling circuit of the nurse mobile robot.Meanwhile,the power supply part is also extended to guarantee the motor power supply of the L293D. The result of actual controlling test is good.
